I would appreciate some feedback on the best product for changing oil. I have a 3 cyl Yanmar. I have seen several oil change pumping products. The suction type like the OIL BOY seem very attractive as they look like they do a fairly good job without a lot of mess. I would enjoy hearing some opinions.

Good call
Hi Liam - I have used the Oil Boy (or maybe it's Big Boy?) for years and it works as advertised. But don't think you won't have some oil somewhere to clean up - I recommend having plenty of oil absorbant pads and a roll of paper towels handy just in case! Best, Trevor

Jabsco Pump
I built a connector from a Jabsco hand pump directly to the fitting on the tube that connects to the bottom of the oil pan. It involved finding a male fitting that screws into the oil tubing fitting with a barb to fit the hose to the hand pump. We just hook it up and pump the oil into some old OJ containers. Very simple, no electricity involved. Stu

Oil Boy, not Big Boy
Oil Boy and Big Boy are different. I like my Oil Boy. It's very well made and easy to use. Here's a link to it at West Marine.

The important thing is to get the oil warm enough
to flow easily, Usually motor over to the pumpout station and fuel dock first or do it after returning from a sail.

couple of questions
Paul. Have you tried to use it to pump water? I have a small area in one of my bilges where water gets trapped and can't get to the bilge pump. It is too tight to get a sponge into so in the past I used my Smith 12 volt oil change pump to get it all out. I have now messed up my oil change pump probbly because I let it pump dry too long. Secondly the problem I had changing the oil with my 12 v pump was that I could not "feel" when the hose in the dipstick tube hit bottom. I know I had more than enough hose and I'm sure that it went in and curled up so that I really didn't get all the oil out. Wouldn't there be the same problem with the vacuum type pumps?

Answer to Bill
I'm not Paul, but I don't see any reason that my Oil Boy wouldn't work with water. I also had the problem of a curling hose with my previous pump, but not with the Oil Boy. Its hose is flexible enough to follow the curves in the dipstick tube, but stiff enough to not curl up in the sump.

Does your oil pan have a drain plug llike cars have,yanmar doesn't seem to put a drain plug any more,I have plenty of room under the engine and I am thinking of adding a drain plug during winter storage is the pan metal or aluminium. nick

Oil Changer
I use one of those impeller pump devices (I think made by Jabsco, but not sure) that you put in an electric drill, insert the tube into the dipstick hole, hit start and it sucks out all your oil in a few seconds. Also, I use the same device to suck out the transmission oil (Yanmar 2GM20F). The device costs about $20 at BoatUS/West and really makes the job simple. Just bring along a big plastic bag to drop the device in after using it in order to keep it from dripping oil where you don't want it.

It's really very simple...
I removed the oil pan and drilled and tapped a hole in the back of the pan, inserted a petcock and reinstalled the pan. Now I simply warm the engine and open the petcock, drain the oil, change the filter and refill. Takes all of 10 minutes and no problems. Big plus, besides the ease of doing it, ALL the oil and sludge comes out.
